Numerical study on local scour characteristics around submarine pipelines in the Yellow River Delta silty sandy soil under waves and currents
• Based on the renormalized group κ-ϵ turbulence model and Stokes fifthorder wave theory, a three-dimensional numerical model of currents and waves–submarine pipeline–silty sandy seabed was established for scouring. • The reliability and accuracy of the numerical model were verified against experimental data measured from a self-built waveflow flume. • Computational and experimental investigations were conducted on the local scour development and characteristics of submarine pipelines in the Yellow River Delta silty sandy seabed. The effects of different water depths, flow velocities, and pipeline suspension heights on the local scour characteristics of submarine pipelines were compared and analyzed.
